Allan v Renfay Projects Pty Ltd

The dispute in Allan v Renfay Projects Pty Ltd arose when homeowner Allan alleged that the builder Renfay Projects Pty Ltd had breached statutory and contractual warranties in the construction of a residential building. The case was heard and determined by the NSW Supreme Court. The homeowner sought damages for various defects, including a leaking roof, which he attributed to defective design. The builder denied liability, arguing that the defects did not arise from the design but were instead due to other factors.

The primary legal issues before the court were the proper interpretation of the statutory warranties under the Home Building Act 1989 (NSW) as incorporated in the Master Builders Association Residential Building Contract, and the extent to which the builder could be held liable for failures caused by design. Specifically, the court had to determine the meaning of the phrase "relates solely" in Schedule 2 cl 2(2) of the Act and the concept of "specific purpose or result" in s 18B(1)(f). The court also had to consider the extent to which the builder could be held responsible for design-related failures, drawing on the precedent set in The Owners – Strata Plan No 66375 v King.

The court found that the defects in question, particularly the leaking roof, were not solely attributable to defective design but were influenced by other factors. Therefore, they did not "relate solely" to the design as required by the statutory provisions. The court held that the builder could not be held liable for failures that were not exclusively design-related. It distinguished and explained the earlier case of The Owners – Strata Plan No 66375 v King, clarifying the scope of builder liability under the Act. Based on this reasoning, the court dismissed the homeowner's claim and ordered that the homeowner pay the builder's costs of the proceedings.
